i have bought a khyber 98 in ash grey colour couple of months ago n changed the oil, oil filter n air filter the day i got it. the prob is that the oil which the previous owner was using in it got black alot n was stick to the inside of engine and at that time i didnt noticed but now its time to change the oil again so some 1 suggested me to put lil diesel in engine then flush it out then put lil new engine oil n flush it out then put the engine oil in it i just wana know that is it good to put diesel in engine for a flush in order to clean the engine from inside
m using caltex havoline cng oil.
